近几十年江苏省经济发展过程中的耕地损耗时空分异特征研究

通过对江苏省经济发展与耕地损耗动态变化的分析,提出经济发展耕地代价的计算方法,并从时空角度定量分析了江苏省经济发展与耕地损耗的关系,结果表明:经济发展与耕地损耗具有较大的相关性,工业产值的增加对耕地损耗具有最大的驱动作用;经济增长模式仍属于资源消耗型,但土地利用集约度在逐渐增强;耕地代价呈现出以宿迁为原点中心的圈层式递减趋势;在加强经济发达地区耕地保护的同时,更应突出对经济相对落后地区的耕地保护.

Loss of Cultivated Land in the Process of Economic Development in Recent Decades

Based on an analysis of ec onomic development and dynamic change of cultivated land loss, this paper introduces a method for land price computation and conducts a quantitative analysis of the relationship between economic development and cultivated land loss, concluding that the increase of the industrial output is the biggest driving force for cultivated land loss, that the economic growth of Jiangsu Province was at the cost of the resources, that the land use intensity has been strengthened, and that protection of cultivated land is more important in the regions where economy is relatively backward in our country.
